SPDT Relays
Single-pull/double-throw relays are ideal for applications where local or remote
contacts are required for control of electrical loads. They are suitable for use with
HVAC, temperature control, fire alarm, security, energy management, and lighting
control systems. Each relay position contains a high-intensity LED which, when
illuminated, indicates the relay coil is energized. Individual relay circuits may be
snapped apart from standard four- or eight-position modules, and are also available
in a single-circuit configuration. The common power to each relay position is bussed
on the printed wiring board, which permits power to be connected only once per
multi-position module.
Single-Voltage Manual Override Relays
MR-600 series relays provide SPDT, 10-Amp contacts with manual override capability by means of an ON-AUTO-OFF
switch. The relay requires a 24Vac or 24Vdc power source supplied by the controlling system. With the switch in the ON
position the power relay is energized. With the switch in the AUTO position the relay is allowed to operate as signaled
by the controlling system. With the switch in the OFF position the relay cannot be energized.

Three-Voltage Control Relays
MR-800 Series relays provide SPDT 10-Amp contacts that may be operated by one of three input control voltages:
24Vdc, 24Vac or 115Vac.

Four-Voltage Control Relays
MR-700 Series relays provide SPDT 10-Amp contacts that may be operated by one of four input control voltages: 12Vdc,
12Vac, 24Vdc, or 24Vac.

Three-Voltage Encapsulated Control Relays
PAM-1 relays provide 10-Amp Form C contacts. The relay may be energized by one of three
input voltages: 24Vac, 24Vdc, or 115Vac. The PAM-1 may be mounted with double-sided
adhesive tape, a self-tapping screw, or loosely placed in a backbox.
